10.4 Establish Normal Hearing Level Thresholds
A test facility may use the default normal hearing level thresholds or establish facility-specific normal hearing level
thresholds. The thresholds are established by conducting a series of tests on normal hearing adults using facility equip-
ment. Use this procedure to enter the facility threshold values in ICS Chartr EP 200.
Once the biological calibration (i.e., listening check) is performed and correction value is determined, then changes can be
made in the Threshold Adjustments table.
If the softest level normal hearing people hear is 20 dB, add this value to the value in the system (i.e., the Click value
would change from 0 to 20). This makes 0 dB on the dial equal to 0 dB. This will reduce the maximum output from what it
was before the change was made. You will not have a correction factor if the change is made.
A. Select Calibration > Threshold Adjustments from the Menu bar to display the Threshold Adjustments dialog box.
B. Select a transducer and type the new values for the facility.
